The words "no, it does not matter" form a sort of principle to adopt in life. Of course there are things which obviously do matter. It matters a great deal if you do not follow your ideal, if you have made a slip of the tongue, or any other shortcoming. But it does not matter if somebody else is not following the same ideal as you; you cannot alter his plan of life, nor his opinions, and so they cannot matter to you. The Sufi's way is to seek unity and not get lost in variety. People can take up philosophy, theosophy, and all the rest if they wish, but these are not the concern of the Sufi. He will let those people restrict themselves if they wish to be restricted. His path is the direct path towards unity, and his is the path of balance. If a person compares two pictures and calls the one good and the other poor, let him be. It does not help if the fire in his ego-faculty is aroused. Some day he will see.
